Finite Element Analysis Of Large Blast Furnace Shell Structure

In the text, the classification, range and mode of load under the regular productioncondition was analyzed, the5500m3blast furnace finite element model was erected.Based on the finite element model analysis, the integral and local stress and deformationof the blast furnace shell, and the influence of the big holes to the blast furnace shellwas discussed. And more, the appropriate advice of the thickness of shell, the form anddimension of the holes was making out.The investigation takes the forms as the following parts:(1) Analysis to the loadsClassify the loads on the shell of the blast furnace and contrast to the researchproduction. Make certain the mode and range of load through the discussion to theiron-making major. Make sure the calculate parameter of the wind and the earthquake.(2) Integral finite element model of the blast furnace shellAccording to the shape and holes of the blast furnace provided by iron-makingmajor, erect the integral finite element model of the blast furnace with the finite elementprograms MIDAS and ANSYS, and apply the loads to the finite element model,.(3) Analysis to the resultThe load combination was discussed in the text. Through the contrast to the resultscalculated by MIDAS and ANSYS, make sure the accuracy of the results. And more,analyze the stress and the deformation of the blast furnace shell.(4) Conclusion and advisementThrough the previous analysis, the thickness of the blast furnace shell wasappraised, and the influence of the big holes to the blast furnace shell was dicussed..
